Filed May 5, 1959, Ser. No. 811,158 1 Claim. (Cl. 21S-11) This inventionrelates to an infants nursing bottley and has as its primary object theprovision of an improved nursing bottle provided with a readilydetachable nipple and characterizedv by means whereby the nipple may bereadily and expeditiously stored inside the bottle when not in use, thusreducing the possibility of losing or misplacing the nipple.

An additional object of the invention is the provision of a reversiblenipple-holding member which can be secured to the bottle for retainingthe nipple in either operative or storage position.

Still another object of the invention resides in the provision of aprotective cap which may be placed over the nipple when in storageposition.

A still further object of the invention resides in the provision of sucha bottle having an air vent provided with a spring-biased check valvefor the purpose of facilitating the withdrawal of the contents of thebottle by the infant.

Still another object of the invention is the provision of such a bottleprovided with readily removable top and bottom caps, and characterizedby the absence of crevices or corners apt to collect dirt, thusfacilitating the cleaning and sterilizing of the bottle.

Still another object of the invention is the provision of such a nursingbottle which is sturdy and durable in construction, reliable andefficient in operation, and relatively simple and inexpensive tomanufacture, assemble and utilize.

Still other objects reside in the combinations of elements, arrangementsof parts and features of construction, all as will be more fully pointedout hereinafter and disclosed in the accompanying drawing, wherein thereis shown a preferred embodiment of this inventive concept.

In the drawing:

FIGURE 1 is an exploded side elevational view of one form of nursingbottle, partially in section, showing the nipple in operative or nursingposition.

FIG. 2 is a longitudinal vertical sectional view of the ige PatentedJury' 1e, rss2 a depending annular skirt 26, which is preferably`knurled to provide a finger gripping portion, and has at its'lowerextremity an inwardly extending flange 27 which is adaptbotle of FIG. lshowing the nipple in storage position and a protective cap in place,the check valve in the base of the bottle being shown in closedposition, and

FIG. 3 is a fragmentary sectional view of the check valve in openposition.

Similar reference characters refer to similar parts throughout theseveral views of the drawing.

Having reference now to the drawing in detail, there is generallyindicated at 10 a nursing bottle or the like, of generally cylindricalconguration, provided at its upper end with external threads 11, belowwhich threads is an external annular bead 12. The lower end of thebottle 10, which may be comprised of glass, plastic, metal or otherdesired substance, is also provided with external threads 13.

A nipple retaining cap 14 includes a horizontal flange 15 provided witha relatively large central aperture 16 and a depending vertical skirt17, internally threaded to engage the external threads 11 at the top ofthe bottle, having internal threads 18 adapted to co-act with thethreads 11.

'I'he nipple 19 includes an end portion 20' adapted to be y engaged bythe mouth of the infant, and an enlarged boss ed to be engaged over thebead 12 to` hold the cap in position. v

The lower end of the bottle is provided with a closure cap generallyindicated at 30 which .includes an internally threaded skirt 31 adaptedto engage the threads 1'3. The cap l30 has a centrally positioned,upwardly extending boss 32 adapted to be positioned interiorly of thebottle, through which boss extends a vent port 33 which extends into acountersunk bore 34 having a tapered lower extremity 35 adapted for thereception of the point 36 of a one-way check valve. The valve 36includes a stem 37, which is surrounded by a compression spring 38 whichseats in the bore 34, the upper end of the spring being engaged by anannulus 39 which is held in position in the top of the bore by means ofa knurled cap member 40. The member 4l) is provided with a ventperforation 41.

The bottom of the end cap 30 is countersunk to provide an outer ange 42and an inner flange 43 which surrounds the vent 33. v

From the foregoing, the use and operation of the device should bereadily understandable.

When it is desired to use the bottle, the cap 25 is removed and thenipple 19 is placed in the position shown in FIG. 1, with the retainingmember 14 holding the same in position 'by means of the engagement ofthe flange with the rim 23.

The bottle Iis then lled with milk or other desired liquid, and is readyfor use. The check valve 35 permits the admission of air into the bottlefor venting purposes, facilitating the withdrawal of the liquid, andpreventing to some extent the possibility of the infants developingcolic, by the provision of some fluid in the bottle at all times.

Obviously the caps 3l) and 14 may be removed for cleaning the bottleafter use, and replaced with the nipple in the storage position as shownin FIG. 2, the member 14 serving to hold the nipple in storage position,and the protective cap 25 serving to protect the nipple in substantiallysterile condition.

From the foregoing it will now be seen that there is herein provided animproved infants nursing bottle which accomplishes all of the objects ofthis invention including many advantages of great practical utility andcommercial importance.

As many embodiments may be made of this inventive concept, and as manymodifications may be made in the embodiment herein shown and described,it is to be understood that all matter herein is to be interpretedmerely as illustrative and not in a limiting sense.

We claim:

In an infants nursing bottle, in combination, a cylindrical tubular bodyportion of at least substantially uniform cross section throughout itslength and open at both ends, external threads adjacent one end'of saidbody, an external bead on said body spaced inwardly from said threads, anipple having a marginal ilange adapted to seat on said one end of saidbody, a nipple retaining member having an internally threaded skirt forengaging the threads on said body and an inwardly extending flange forengaging the tlange on said nipple to secure said nipple in operativeposition on said one end of said body, said inwardly extending tlangeengaging the flange on said nipple with said nipple inverted andextending into said body in inoperative position to secure said nipplein unliexed condition in inoperative position, a protective flat top capof resilient material having a skirt terminating in an inwardlyextending Iange, said last named ange engaging said bead to hold `saidcap Yin position over `said retaining mem- Iber and over s'aid nipple ininoperativepos'ition,"external threadsiadjacent the opposite end of saidbody, a closure threadedlyrengaging said last named threads, a centralboss o'n said closure projecting Within said body, at leastsubstantially th'eent'ire outer side Wall of said boss being concave tofacilitate cleaning,va'th'readed bore extending through said Iboss andsaid'closure to provide a vent, a valve seat in said bore, a valveslidably received vin said bore, a spring for urging said valveinto'engagernent with saidseat, aplug threadedlyv received in the innerend of said bore for retaining said spring and said valve in said bore,and an aperture in -said plug communicating with said bore and theinterior of said body to permit flow of 4 air during use of said bottle,said valve closing said bore during periods of non-use.
